- the 3rd Generation Partnership Project (3GPP) will begin to introduce research on low power wake-up receivers (LP WUR)/low power wake-up signals (LP-WUS) in mobile cellular systems at Rel-18.
- the basic working principle of LP WUR is that the receiving end includes a first module and a second module.
- the first module is the main communication module, which is used to send and receive mobile communication data
- the second module is the low power wake-up receiving module, which is used to receive the above wake-up signal.
- the terminal turns on the low power receiving module to monitor LP-WUS and turns off the main communication module.
- the network will send a wake-up signal to the terminal.
- the terminal After the terminal monitors the wake-up signal through the low power receiving module, it triggers the main communication module from off to on after a series of judgments (at this time, the low power receiving module enters the off state from the working state).
- Low The power consumption wake-up receiving module can be turned on continuously or intermittently, and can receive the low power consumption wake-up signal when turned on.
- the RF (Radio Frequency, RF) and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception.
- This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, but only relies on passive matching filtering and signal processing with low power consumption.
- the near-zero power receiver can be activated to receive the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.
- This wake-up signal is usually some relatively simple on-off keying (OOK) signal, as shown in Figure 3, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes.
- OSK on-off keying
- the OOK signal can be generated by the OFDM signal generation method, for example, the sending or not sending of the OFDM modulated sequence indicates ON/OFF in the time domain.
- the OOK signal can be received by a receiver with lower power consumption, but the receiving performance and coverage of such receivers are poor.
- the OFDM modulated sequence with ON modulation can further carry information through different sequences, for example, two sequences represent 0 and 1 information respectively, or four sequences represent 00, 01, 10, and 11 information respectively. As shown in Figure 4, part of the information is carried through OOK modulation, and the other part of the information is carried through the OFDM sequence of the ON level.
- the measurement behavior requirements of the NR system in the related technology include: the terminal needs to perform RRM measurement periodically, and the RRM measurement is a measurement performed by the main receiver based on the synchronization signal/physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH block, SSB).
- the synchronization signal/physical broadcast channel signal block or synchronization signal block
- SSB Synchronization Signal and PBCH block
- the terminal does not need to periodically perform paging to receive the physical downlink control channel (PDCCH), but periodic measurements still require the use of a main receiver, which makes it impossible to reduce the overall power consumption of the terminal. Therefore, the power saving gain brought about by the introduction of LP-WUR is limited.
- PDCCH physical downlink control channel
- RRM radio resource management
- an embodiment of the present application provides a measurement switching method, including:
- Step 501 The terminal obtains a first measurement result corresponding to a first measurement behavior
- Step 502 The terminal determines whether to switch to a second measurement behavior according to the first measurement result and a measurement switching threshold;
- the measurement switching threshold is related to the type of the low power consumption receiver of the terminal and/or the type of the signal measured by the low power consumption receiver.
- the measurement behavior can be accurately switched based on the type of low-power receiver to achieve a reasonable balance between different measurement accuracies and low power consumption.
- the first measurement behavior or the second measurement behavior includes at least one of the following:
- A12 using the low power receiver to perform measurement and using the receiver of the main communication module to perform measurement of the first cycle;
- the second period is smaller than the first period.
- the measurement of the first cycle using the receiver of the main communication module can be understood as the relaxed cycle measurement using the receiver of the main communication module
- the measurement of the second cycle using the receiver of the main communication module can be understood as the conventional cycle measurement or the non-relaxed cycle measurement using the receiver of the main communication module. It can be seen that the power consumption of the measurement of the first cycle using the receiver of the main communication module is lower than the power consumption of the measurement of the second cycle using the receiver of the main communication module.
- the switching involved in the embodiments of the present application may include: switching from A11 to A12, switching from A11 to A13, switching from A12 to A13, switching from A13 to A12, switching from A13 to A11, and switching from A12 to A11.
- the measurement switching thresholds corresponding to different switching processes are usually different.
- the measurement switching threshold corresponding to the switching from A11 to A13 is TH13
- the measurement switching threshold corresponding to the switching from A13 to A11 is TH31
- TH13 is different from TH31.
- the measurement behavior can be divided into switching from low-power measurement behavior to high-power measurement behavior and switching from high-power measurement behavior to low-power measurement behavior.
- switching from A11 to A12, switching from A11 to A13, and switching from A12 to A13 can be regarded as switching from low-power measurement behavior to high-power measurement behavior
- switching from A13 to A12, switching from A13 to A11, and switching from A12 to A11 can be regarded as switching from high-power measurement behavior to low-power measurement behavior.
- the first measurement result is greater than or equal to the measurement switching threshold, it is determined to switch to the second measurement behavior. If the first measurement result is less than the measurement switching threshold, it is determined not to switch to the second measurement behavior, and the first measurement behavior is continued to be maintained. It can be understood that the measurement result is better, that is, the coverage is better, and there is no need to use high-power measurement behavior, so it can be switched to low-power measurement behavior; or, in the case of switching from low-power measurement behavior to high-power measurement, if the first measurement result is less than or equal to the measurement switching threshold, it is determined to switch to the second measurement behavior.
- the first measurement result is greater than the measurement switching threshold, it is determined not to switch to the second measurement. Behavior, continue to maintain the first measurement behavior, it can be understood that the measurement result is poor, indicating that the coverage is poor and the measured value is low. In order to improve the measurement accuracy, it is switched to high power consumption when it is below the threshold.
- the method further includes at least one of the following:
- the terminal uses the low power consumption receiver to perform measurement, the terminal needs to monitor the low power consumption wake-up signal.
- the terminal uses the receiver of the main communication module to perform measurement, the terminal needs to monitor the paging PDCCH or PEIPDCCH.
- monitoring behavior that is, the switching of monitoring behavior; for example, using a low-power receiver to monitor the low-power wake-up signal is considered as monitoring behavior 1, and using the receiver of the main communication module to monitor the paging PDCCH or PEIPDCCH is considered as monitoring behavior 2. If it is higher than the measurement switching threshold, monitoring behavior 1 is used, and if it is lower than the measurement switching threshold, monitoring behavior 2 is used.
- the measurement result of the low-power receiver is lower than the measurement switching threshold A, it indicates that the channel quality is poor.
- the performance of the terminal using the low-power receiver to monitor the low-power wake-up signal will also deteriorate.
- the measurement result of the main communication module receiver is higher than the measurement switching threshold B, it indicates that the channel quality is good.
- the terminal can ensure the detection performance even if it uses a low-power receiver to monitor the low-power wake-up signal. In this case, switching to the low-power receiver to monitor the low-power wake-up signal ensures performance while reducing the power consumption of monitoring.
- the above measurement switching thresholds may also be different and may be configured separately.
- the measurement accuracy for different receiver types is different, so the measurement switching thresholds are also different. This allows for more accurate judgment of channel quality.
- the method further includes at least one of the following:
- the third period is greater than or equal to the fourth period.
- the receiver of the main communication module is used after switching, it is necessary to determine the period of the receiver of the main communication module used according to the relationship between the first measurement result and the measurement switching threshold. If the first measurement result measured using a low-power receiver is greater than or equal to the measurement switching threshold, the channel quality is good, and the receiver of the main communication module can use a longer period for measurement, that is, the measurement does not need to be too frequent, and the measurement can be relaxed; if the first measurement result is lower than the measurement switching threshold, the channel quality is poor, and the receiver of the main communication module uses a shorter period for measurement to ensure the accuracy of the measurement, that is, no measurement relaxation is performed or the measurement is performed in a longer period.
- the third cycle and the fourth cycle may have the same concept as the first cycle described above, except that the cycle lengths are different.

第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)将在Rel-18开始在移动蜂窝系统中引入低功耗唤醒接收机(Low Power Wake Up Receiver,LP WUR)/低功耗唤醒信号(Low Power Wake Up Signal,LP-WUS)的研究工作,LP WUR的基本工作原理为接收端包含第一模块和第二模块。具体如图2所示,第一模块为主通信模块,用于移动通信数据的收发,第二模块为低功耗唤醒接收模块,用于接收上述唤醒信号。终端在节能状态下开启低功耗接收模块来监听LP-WUS且关闭主通信模块。当有下行数据到达时,网络会发送唤醒信号给终端,终端通过低功耗接收模块监听到唤醒信号后通过一系列的判断后触发主通信模块从关闭到开启,(而此时低功耗接收模块从工作态进入关闭状态)。低
功耗唤醒接收模块可以连续开启,或间歇性开启,在开启时可接收低功耗唤醒信号。
二、LP-WUS或近零功率唤醒信号(Almost Zero Power wake up signal,AZP-WUS)
为了减少终端在待机状态下的接收活动,使得射频(Radio Frequency,RF)和基带(MODEM)模块真正的关闭从而大大降低通信接收的功耗,可以通过在终端的接收模块中引入了一个近“零”功率的接收机从而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理,只靠被动的匹配滤波和较小功耗的信号处理。
在基站侧,通过按需(on-demand)触发唤醒信号,就可以激活近“零”功率的接收机获知激活的通告,从而触发终端内部的一系列流程,例如打开射频收发以及基带处理等模块。
这种唤醒信号通常来说是一些比较简单的开关键控(on-off keying,OOK)信号,如图3所示,那样接收机就可以通过简单的能量检测,以及之后的可能的序列检测识别等过程获知唤醒通告。
由于相关技术中的新空口(New Radio,NR)系统中,普遍采用正交频分复用(Orthogonal frequency division multiplex,OFDM)的信号调制方式。那么可以采用OFDM的信号生成的方式生成OOK信号,例如通过OFDM调制的序列的发送或者不发送,表示时域上的ON/OFF。OOK信号可以使用较低功耗的接收机进行接收,但是这类接收机的接收性能较差,覆盖也较差。
进一步的,在调制ON的OFDM调制的序列可以进一步的通过不同的序列携带信息,例如两个序列分别代表0、1信息,或者4个序列分别代表,00、01、10、11信息,如图4所示,一部分信息通过OOK调制,另一部分信息通过ON电平的OFDM序列携带。
由于解调出OFDM序列需要具备OFDM信号接收能力的接收机,一般而言这类接收机的解调性能更好,好于只能解OOK信号的这类低功耗接收机。
三、NR系统的测量行为
相关技术中的NR系统的测量行为要求,包括:终端需要周期性的进行RRM测量,RRM测量为基于同步信号/物理广播信道信号块(或同步信号块)(Synchronization Signal and PBCH block,SSB)的使用主接收机进行的测量。
在引入的LP-WUR的情况下,终端可以不必周期性的进行寻呼(paging)物理下行控制信道(Physical downlink control channel,PDCCH)的接收,但是周期性的测量仍然需要使用主接收机,使得终端的整体功耗无法降低,因此引入LP-WUR带来的省电增益有限。
而低功耗接收机进行无线资源管理(Radio resource management,RRM)测量的精度又比较低,在信道条件较差的情况下,低功耗接收机进行RRM测量的功耗会显著下降,那么为了在追求低功耗和追求测量精度之间做更好的平衡。需要根据信号条件采用不同的测量行为,以达到在不同的测量精度和低功耗之间的合理平衡。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的测量切换、信息
传输方法、装置、终端及网络侧设备进行详细地说明。
如图5所示,本申请实施例提供一种测量切换方法,包括:
步骤501,终端获取第一测量行为对应的第一测量结果;
步骤502,终端根据所述第一测量结果以及测量切换门限,确定是否切换为第二测量行为;
其中,所述测量切换门限与所述终端的低功耗接收机的类型和/或低功耗接收机测量的信号类型相关。
需要说明的是,通过基于第一测量行为对应的第一测量结果及与低功耗接收机的类型相关的测量切换门限,确定是否切换为第二测量行为,以此能够基于低功耗接收机的类型准确进行测量行为的切换,以达到在不同的测量精度和低功耗之间的合理平衡。
可选地,一种实现方式中,所述第一测量行为或所述第二测量行为包括以下至少一项:
A11、使用低功耗接收机进行测量;
A12、使用低功耗接收机进行测量以及使用主通信模块的接收机进行第一周期的测量;
A13、使用主通信模块的接收机进行第二周期的测量;
其中,所述第二周期小于所述第一周期。
这里需要说明的是,使用主通信模块的接收机进行第一周期的测量可以理解为是使用主通信模块的接收机进行放松的周期测量,而使用主通信模块的接收机进行第二周期的测量可以理解为是使用主通信模块的接收机进行常规的周期测量或者是非放松的周期测量。可以看出,使用主通信模块的接收机进行第一周期的测量的功耗要低于使用主通信模块的接收机进行第二周期的测量的功耗。
需要说明的是,本申请实施例中所涉及的切换可以包括:A11向A12切换、A11向A13切换,A12向A13切换,A13向A12切换,A13向A11切换,A12向A11切换,不同的切换过程所对应的测量切换门限通常是不同的。例如,A11向A13切换对应的测量切换门限为TH13,而A13向A11切换对应的测量切换门限为TH31,TH13与TH31不相同。
需要说明的是,基于上述的测量行为,可以将测量行为划分为低功耗测量行为向高功耗测量行为的切换以及高功耗测量行为向低功耗测量行为的切换,例如,A11向A12切换、A11向A13切换,A12向A13切换可以看成是低功耗测量行为向高功耗测量行为的切换;A13向A12切换,A13向A11切换,A12向A11切换可以看成是高功耗测量行为向低功耗测量行为的切换。
例如,在高功耗测量行为向低功耗测量行为的切换的情况下,若第一测量结果大于或等于测量切换门限,确定切换为第二测量行为,若第一测量结果小于测量切换门限,则确定不切换为第二测量行为,继续维持第一测量行为,可以理解为,测量结果较好,即覆盖较好,没有必要使用高功耗的测量行为,所以可以切换到低功耗的测量行为;或者,在低功耗测量行为向高功耗测量的切换的情况下,若第一测量结果小于或等于测量切换门限,确定切换为第二测量行为,若第一测量结果大于测量切换门限,则确定不切换为第二测量
行为,继续维持第一测量行为,可以理解为,测量结果较差,说明覆盖较差,测量出来的数值较低,为了提高测量精度,低于门限就往高功耗切换。
可选地,一种实现方式下,所述方法,还包括以下至少一项:
A21、在使用低功耗接收机进行测量的情况下,监听低功耗唤醒信号;
也就是说,不管是在第一测量行为还是第二测量行为下,终端若使用低功耗接收机进行测量,则终端需要监听低功耗唤醒信号。
A22、在使用主通信模块的接收机进行测量的情况下,监听寻呼PDCCH或者寻呼提前指示(paging early indication,PEI)PDCCH;
也就是说,不管是在第一测量行为还是第二测量行为下,终端若使用主通信模块的接收机进行测量,则终端需要监听寻呼PDCCH或者PEIPDCCH。
进一步地,对于测量行为切换而言,也即监听行为的切换;例如,使用低功耗接收机监听低功耗唤醒信号认为是监听行为1,使用主通信模块的接收机监听寻呼PDCCH或者PEIPDCCH认为是监听行为2,若高于测量切换门限则采用监听行为1,低于测量切换门限则采用监听行为2。
例如,当低功耗接收机测量结果低于测量切换门限A的情况下,表示信道质量较差,此时终端采用低功耗接收机监听低功耗唤醒信号的性能也会变差,这种情况下,可以切换到主通信模块接收机直接进行寻呼PDCCH或者PEIPDCCH的监听,以保证寻呼可靠性。反之,如果主通信模块接收机测量结果高于测量切换门限B的情况下,表示信道质量较好,此时终端即使采用低功耗接收机监听低功耗唤醒信号也能保证检测性能,这种情况下,切换到低功耗接收机进行低功耗唤醒信号的监听,在保证性能的同时,也降低了监听的功耗。
需说明的是,对于不同的接收机类型,上述测量切换门限也可以是不同的,可以是分别配置的。针对不同的接收机类型的测量精度不同,所以测量切换门限也是不同的。这样可以更准确的判断信道的质量。
可选地,一种实现方式下,所述方法,还包括以下至少一项:
A31、如果所述第一测量结果大于或等于测量切换门限,则确定主通信模块的接收机使用第三周期进行测量;
A32、如果所述第一测量结果小于测量切换门限,则确定主通信模块的接收机使用第四周期进行测量;
其中,所述第三周期大于或者等于所述第四周期。
此处可以理解为,若切换后使用主通信模块的接收机,则需要根据第一测量结果与测量切换门限的关系来确定所使用的主通信模块的接收机的周期。如果使用低功耗接收机测量的第一测量结果大于或等于测量切换门限,则信道质量较好,则主通信模块的接收机可以使用较长的周期进行测量,即测量不用过于频繁,可以进行测量放松;如果第一测量结果低于测量切换门限,则信道质量较差,则主通信模块的接收机使用较短的周期进行测量,保证测量的准确性,即不进行测量放松或者进行周期较长的方式测量。
可选地,该第三周期和第四周期可以与上述的第一周期的概念相同,只不过周期长度不同。
需说明的是,对于不同的接收机类型,上述测量切换门限也可以是不同的,可以是分别配置的。针对不同的接收机类型的测量精度不同,所以切换门限也是不同的。这样可以更准确的判断信道的质量。

B12、具备能够解调开关键控信号以及检测调制开信号的调制序列的能力;
需要说明的是,此种类型可以理解为是类型2的接收机,即此种类型的低功耗接收机既能解调开关键控信号也能检测调制开信号的调制序列,或者也可以理解为:此种类型的低功耗接收机具备既能解调开关键控信号也能检测调制开信号的调制序列的能力。
B13、具备能够解调开关键控信号,不能检测复数信号序列的能力;
需要说明的是,此种类型可以理解为是类型3的接收机,即此种类型的低功耗接收机能够解调开关键控信号,但是不能检测复数信号序列。
B14、具备能够检测复数信号序列的能力;
需要说明的是,此种类型可以理解为是类型4的接收机,即此种类型的低功耗接收机能够检测复数信号序列。
可选地,一种实现方式下,该具备能够检测复数信号序列的能力,包括:具备能够解调开关键控信号以及检测复数信号序列的能力。
可选地,一种实现方式下,所述复数信号序列包括:时域复数信号序列,频域复数信号序列中的至少一项。从发送端角度,该复数信号序列可以是时域或者频域定义的信号序列。从接收端角度,该复数信号序列是在时域检测的,即接收端可以不具备快速傅里叶变换(fast Fourier transform,FFT)变换能力,在时域完成该复数信号序列的检测。
可选地,上述的调制序列包括以下至少一项确定的复数序列或者以下至少两项生成的实数或者复数序列的相乘确定的序列:
M序列、ZC序列、gold序列、恒包络零自相关(Const Amplitude Zero Auto-Corelation,CAZAC)序列、由第一调制方式对应的星座点产生的序列;
其中,所述第一调制方式包括以下至少一项:二进制相移键控(Binary Phase Shift Keying,BPSK)调制、pi/2 BPSK调制、正交相移键控(Quadrature Phase Shift Keying,QPSK)调制,包含16种符号的正交振幅调制(16QAM),包含64种符号的正交振幅调制(64QAM)、包含256种符号的正交振幅调制(256QAM)、包含1024种符号的正交振幅
调制(1024QAM)、包含4096种符号的正交振幅调制(4096QAM)。
可选地,上述提到的星座点指的是:正交振幅调制的符号,即正交振幅调制的符号即为星座点,例如,16QAM调制可产生16个调制符号,该16个调制符号也可以称为16QAM调制方式对应的星座点。
可以理解为:调制序列可以为基于M序列、ZC序列、gold序列、或CAZAC序列或由第一调制方式对应的星座点产生的序列生成的复数序列;或者,调制序列也可以为基于M序列、ZC序列、gold序列、CAZAC序列和由第一调制方式对应的星座点产生的序列中的至少两项生成的实数或者复数相乘生成的序列。
可选地,上述的复数信号序列包括以下至少一项确定的复数序列或者以下至少两项生成的实数或者复数序列的相乘确定的序列:
M序列、ZC序列、gold序列、恒包络零自相关CAZAC序列、由第二调制方式对应的星座点产生的序列;
其中,第二调制方式包括以下至少一项:BPSK调制、pi/2 BPSK调制、QPSK调制、16QAM、64QAM、256QAM、1024QAM、4096QAM。
可以理解为:复数信号序列可以为基于M序列、ZC序列、gold序列、或CAZAC序列或由第二调制方式对应的星座点产生的序列生成的复数序列;或者,复数信号序列也可以为基于M序列、ZC序列、gold序列、CAZAC序列和由第二调制方式对应的星座点产生的序列中的至少两项生成的实数或者复数相乘生成的序列。
需要说明的是,由于相关技术中的NR系统中,普遍采用OFDM的信号调制方式,那么可以采用OFDM的信号生成的方式生成OOK信号,例如通过OFDM调制的序列的发送或者不发送,表示时域上的ON/OFF。OOK信号可以使用较低功耗的接收机进行接收,但是这类接收机的接收性能较差,覆盖也较差。进一步的,在调制ON的OFDM调制的序列可以进一步的通过不同的序列携带信息,例如两个序列分别代表0、1信息,或者4个序列分别代表,00,01,10,11信息,如图4所示。图4中,一部分信息通过OOK调制,另一部分信息通过ON电平的OFDM序列携带。由于具备OFDM信号接收能力的接收机才能够解调出OFDM序列,一般而言这类接收机的解调性能更好,好于只能解OOK信号的这类低功耗接收机。对于上述波形的控制信号,可以存在不同的低功耗接收机的类型,例如存在上述的类型1、类型2、类型3和类型4的低功耗接收机。对于RRM测量,由于类型2或类型4的接收机的能力更强,测量精度也高于类型1或类型3的接收机,那么在进行RRM测量接收机在低功耗接收机和主通信模块的接收机之间切换时,需要考虑低功耗接收机的类型,即解调不同波形的能力分别确定测量切换门限。此外,由于类型2或类型4的接收机基于调制开关键控信号的OFDM信号序列的测量的精度和类型4的接收机基于同步信号块SSB中的信号序列,测量的精度不同。通常低功耗接收机基于SSB中的PSS/SSS的测量精度比基于调制开关键控信号的OFDM信号序列的精度更好,例如定义更高的精度要求,或者对PSS/SSS有精度要求但对基于调制开关键控信号的OFDM
信号序列的测量没有精度要求。那么在进行RRM测量接收机在低功耗接收机和主通信模块的接收机之间切换时,还需要考虑测量信号的类型,即根据测量所使用的信号来分别确定测量切换门限。根据OFDM receiver用LP-SS with overlaid OFDM sequence测量但是RAN4不定义requirement,所以无法保证性能。那么,这种情况下用针对OOK信号的测量切换门限,用户设备(User Equipment,UE)的切换行为更加准确,保证测量性能。
可选的,基于SSB中的信号序列和基于调制开关键控信号的OFDM信号序列测量是不同的接收机能力。

下面对本申请的具体应用举例说明如下。
本申请实施例中提到的RRM测量行为切换主要包括两个方向的切换:一、低功耗的测量行为向高功耗的测量行为切换,二、高功耗的测量行为向低功耗的测量行为切换。上述的A11-A13的测量行为中,A11和A12是功耗较低的测量行为,A13是功耗较高的测量行为。因为使用了低功耗的接收机,低功耗的测量行为的测量精度相对较低,而使用高功耗的接收机由于接收可靠性更高则测量精度较高。
对于低功耗接收机也存在不同类型,对应于不同的接收可靠性、测量精度,本申请实施例中的两类类型的低功耗接收机中,类型2的低功耗接收机的可靠性和测量精度高于类型1的低功耗接收机。对于两种测量精度的低功耗接收机,RRM测量的测量切换门限应该也是不同的。可以针对不同的低功耗接收机的类型设定不同的切换门限,以保证终端在使用低功耗接收机节省功耗和保证RRM测量可靠性之间做更好的平衡。
以A11对应的测量行为到A13对应的测量行为的切换为例,根据低功耗接收机的类型确定测量行为的测量门限,例如,A11对应的测量行为切换到A13对应的测量行为之间的测量切换门限包括以下至少其中一项:
a)类型1的低功耗接收机对应的测量切换门限TH13_1;
b)类型2的低功耗接收机对应的测量切换门限TH13_2。
对于TH13_1和TH13_2可以是网络侧设备根据低功耗接收机的类型分别独立配置。或者网络侧设备配置其中一种低功耗接收机的类型对应的测量切换门限,及门限偏移值DELTA_13,终端可以根据低功耗接收机的类型对应的测量门限值以及门限偏移值确定另外一种低功耗接收机的类型对应的测量切换门限;例如,网络侧设备配置TH13_1以及DELTA_13,则终端可以根据TH13_1以及DELTA_13确定TH13_2。
对于A13对应的测量行为到A11对应的测量行为的切换,根据低功耗接收机的类型确定测量行为的测量门限,例如,A13对应的测量行为切换到A11对应的测量行为之间的测量切换门限包括以下至少其中一项:
a)类型1的低功耗接收机对应的测量切换门限TH31_1;
b)类型2的低功耗接收机对应的测量切换门限TH31_2;
对于TH31_1和TH31_2可以是网络侧设备根据低功耗接收机的类型分别独立配置。或者网络侧设备配置其中一种低功耗接收机的类型对应的测量切换门限,及门限偏移值DELTA_31,终端可以根据低功耗接收机的类型对应的测量门限值以及门限偏移值确定另外一种低功耗接收机的类型对应的测量切换门限;例如,网络侧设备配置TH31_1以及DELTA_31,则终端可以根据TH31_1以及DELTA_31确定TH31_2。
需要说明的是,低功耗接收机存在不同的能力或者类型,对应于不同的接收可靠性、测量精度,本申请的至少一个实施例通过考虑两种类型的低功耗接收机中,类型2的低功耗接收的可靠性和测量精度高于类型1的低功耗接收机,那么对于两种测量精度的接收机,
RRM测量接收机的测量切换门限应该也是不同的,可以针对不同的低功耗接收机的类型设定不同的测量切换门限,以保证终端在使用低功耗接收机时能够在节省功耗和保证RRM测量可靠性之间做更好的平衡。
